Therefore, in the present study, we measured the levels of glycero-LysoPLs (LysoPA, LysoPC, LysoPI, LysoPE, LysoPG, and LysoPS) together with ATX and PS-PLA1 (producing enzymes for LysoPA and LysoPS, respectively) in ascites from subjects with advanced gastric cancers. This evidence concerns the gene PLA1A and gastric cancer.
